PRODUCT USE INFORMATION
As a general rule, the taller a vehicle is, the easier it will roll. Seat belts and shoulder harnesses should
be worn at all times. Avoid situations where a side rollover may occur.
Generally, braking performance and capability are decreased when larger/heavier tires and wheels are used. Take this
into consideration while driving. Do not add, alter, or fabricate any factory or after-market parts to increase vehicle height
over the intended height of the Rough Country product purchased. Mixing component brands is not recommended.
Rough Country makes no claims regarding lifting devices and excludes any and all implied claims. We will not be re-
sponsible for any product that is altered.
This suspension system was developed using a 35x12.50x20 tire on a 20x10 wheel with -18 offset. Different wheel and
tire combinations my be used but different tire manufactures designs may result in a tire width that could result in contact
with the lower control arm and/or front sway bar link in a sharp turn. Please consult with your tire and wheel expert be-
fore purchasing. Also note that if wider tires are desired, offset wheels will be required. If question exist we will be happy
to answer any questions concerning the design, function, and correct use of our products by calling 1-800-222-7023.
NOTICE TO DEALER AND VEHICLE OWNER
Any vehicle equipped with any Rough Country product should have a “Warning to Driver” decal installed on the inside of
the windshield or on the vehicle’s dash. The decal should act as a constant reminder for whoever is operating the vehi-
cle of its unique handling characteristics.
Prior to installing this kit, with the vehicle on the ground, measure the heights of your vehicle. This measurement can be
recorded from the center of the wheel straight up to the top of the inner fender lip. Record the measurements.

1. Confirm that the draglink was adjusted to the center steering wheel BEFORE the vehicle is driven. Failure to do so
will cause a computer error, odd handling, and poor performance.
2. Check all fasteners for proper torque. Check to ensure there is adequate clearance between all rotating, mobile,
fixed and heated members. Check steering for interference and proper working order. Test brake system.
3. Perform steering sweep. The distance between the tire sidewall and the brake hose must be checked closely. Cycle
the steering from full turn to full turn to check for clearance. Failure to perform inspections may result in component
failure.
4. Re-torque all fasteners after 500 miles and recheck after 1000 miles. Alignment must be checked by a qualified me-
chanic. Visually inspect components and re-torque fasteners during routine vehicle service.
5. Readjust headlights to proper settings.
6. Have a qualified alignment center realign the front end, to the factory specifications immediately.
